I have an old steel Benotto that I want to remove the braze ons from. I'm guessing it's Columbus tubing, but not sure. it's a modelo 850 ... probably from the 70's.
what I want to know is, can I use a simple hand held propane torch to remove them? or will I need something hotter?

I really just want to remove the cable and shifter bosses, I don't care so much about the bottle cage nuts.

I searched for this topic but nothing came up, thanks for any help.

Mapp works fine, direct your heat on the object you want removed, when it gets red take a pair of pliers and gently pull the piece off while still applying heat. Don't quench or accelerate the cooling of the frame tube just let it cool at room temp
